Njengomvelisi wombane onobuchule osebenzisa umbane ophantsi onamava eminyaka engama-20 kushishino, iYUANKY iveza uthotho lweDC S7I-Solar DC Miniature Circuit Breaker(MCB), isisombululo esisebenza kakuhle esenzelwe ukhuseleko lwesekethe ye-DC kunye nokwahlulwa, esilungiselelwe ukufakwa kwelanga le-photovoltaic (PV). Ifumaneka kwiimo ze-1P ukuya kwi-4P, ixhasa ii-voltage ezilinganisiweyo ukusuka kwi-DC250V ukuya kwi-1000V, i-current elinganisiweyo ukusuka kwi-6A ukuya kwi-50A, kunye neempawu ze-C-type tripping (7In-15In). Inika amandla okuqhekeza alinganisiweyo e-6kA kunye namandla okuqhekeza afutshane e-15kA kwi-250VDC, kunye nexesha lokuphendula elikhawulezayo kakhulu ≤4ms. Uyilo lwayo olutsha olungena-polarized luphawu oluphambili, lususa umahluko we-polarity ngexesha lokufakelwa kweentambo, lugcina kakhulu ixesha lokufaka kwaye luphephe iimpazamo zeentambo.

Le DC MCB isebenza ngendlela yokukhusela kabini ukujongana neempazamo eziqhelekileyo zenkqubo yeDC. Ukukhusela ukugqithisa, umtya we-bimetallic owakhelwe ngaphakathi ugoba ngobushushu ukuze uqalise indlela yokukhubeka, unqumle isekethe kakuhle phantsi koxinzelelo oluqhubekayo ukuthintela umonakalo wobushushu bezixhobo. Kwiimpazamo zesekethe emfutshane, ukukhululwa kwe-electromagnetic okunovakalelo oluphezulu kusebenza ngoko nangoko, kuphazamisa umbane wesiphako ngaphakathi kwe-≤4ms ukuthintela iingozi ezivela kwi-DC arcs. Ixhotyiswe ngenkqubo yobugcisa yokucima i-DC arc, isombulula umngeni wokuphela kwe-arc kwiisekethe zeDC ngaphandle kwendawo yendalo yokuwela i-zero, iqinisekisa ukuqhekeka okukhuselekileyo nokuthembekileyo. Uyilo lokufakelwa kwe-DIN rail lwenza kube lula ukufakwa ngokukhawuleza kwiikhabhathi zokusasaza eziqhelekileyo.

Ihambelana ngokupheleleyo nemigangatho yamazwe ngamazwe ye-IEC 60947-1/2, le mveliso inesatifikethi se-CE kunye neengxelo zovavanyo lwe-CB ezikhutshwe yi-SEMKO, ihlangabezana neemfuno zokufikelela kwimarike yehlabathi. Isebenza ngokuzinzileyo kwi--5℃ ukuya kwi-+60℃, ilungelelanisa neemeko zokusebenza ezinzima ezahlukeneyo. Isetyenziswa kakhulu kwiinkqubo ze-PV ezibotshelelwe kwigridi/ngaphandle kwegridi, iinkqubo zokugcina amandla ebhetri, iiphaneli zokusasazwa kwe-DC, izitishi zesiseko se-telecom, izixhobo zamandla ezitsha kunye neesekethe zolawulo lwe-DC yemizi-mveliso, lukhetho olufanelekileyo olungabizi kakhulu kubafaki be-PV, abahlanganisi beenkqubo kunye nabathengisi bombane kwihlabathi liphela. Ixhaswa lulawulo oluqinileyo lomgangatho kunye nenkonzo epheleleyo yokuthengisa ngaphambi kokuthengisa kunye nenkonzo emva kokuthengisa, i-YUANKY DC MCB ibonelela ngokhuseleko oluthembekileyo noluhlala ixesha elide kwiinkqubo zombane ze-DC kwihlabathi liphela.
